This is a research graphic synopsis for my recent paper in Angew. Chem., and this was also adopted by the journal as a frontpiece highlight. It was made by my co-author Sahag Voskian.

The long-range organization of a liquid crystal can be controlled by using an additive, which consists of cholesterol units attached to a hydrazone switch. The acid/base-induced rotary

motion in the switch is transmitted to the self-assembled supramolecular host, wherein this information is propagated and amplified. This process alters the photophysical properties of

the host, which results in the change of the readout color from purple to green.

Professor of Chemistry Joseph BelBruno’s Dartmouth lab conducted the research on the technology behind the unique secondhand smoke

sensing device. Smaller and lighter than a cellphone and about the size of a Matchbox car, the device uses polymer films to collect and

measure nicotine in the air.

edition of his bookMixed Models.

More than 300 problems and exercises have been added, so the book can be easily adopted as a

text for graduate studies in statistics. Most of

methods and examples are illustrated with R
